soc/intel/alderlake: Add missing TDP and Power Limits for ADL-S 

Add TDP and Power Limit settings for ADL-S 8+8 150W, 4+0 and 2+0.
The System Agent PCI IDs were not present in older 2.1 revision of
DOC #619501. Now that the mapping of these IDs to SKUs is known, fill
the missing TDPs and Power Limit settings based on DOC #626343.
